The history of drum and bass
Drum and bass began as a musical shift of the United Kingdom breakbeat hardcore and rave scene of the mid 1990s. over the first decade and a half of its existence there have been many iterations in its style, incorporating elements from dancehall, electro, funk, hip hop, house, jazz, pop-created fusion of hardcore, house and techno (also including new beat). This scene existed briefly from approximately 1989-1993, a period of cross-pollination in the UK hardcore sound. This sound did survive in various forms in its mother countries primarily Belgium, the Netherlands and Germany beyond 1992, but by then the general scenes in these countries had moved forwards to trance, industrial techno or gabba (with happy hardcore/hard house being the equivalent 'Belgian Techno' a bench mark sound in the UK). London and Bristol are the two cities which are most associated with Drum and Bass.
Returning to the UK, drum and bass (as jungle) has its direct origins in the breakbeat hardcore part of the UK acid house rave scene. Hardcore DJs typically played their records at fast tempos, and breakbeat hardcore emphasised breakbeats over the 4-to-the-floor beat structure common to house music. Breakbeat hardcore records such as The Prodigy's "Experience" (1992), Genaside II's "Sirens of Acre Lane" (1990), DJ Dextrous' "Ruffneck Biznizz" (1992), Noise Factory's 'Be Free' (1992), Demon Boyz 'Jungle Dett' (1992) and LTJ Bukem's "Demon's Theme" (1992) are generally credited as being among the first to have a recognizable drum and bass sound.
